A full adaptive observer for DC servo motors
(2003)
An adaptive observer estimating all parameters and load torque is proposed for DC servo motors. The observer uses no direct feedback but the adaptation schemes use current and speed measurements. Both the observer and ...
Determination of physical faults in gearbox through vibration analysis
(2003)
Gears are important machine elements that provide motion or power transmission. Accuracy and quality of work done is directly related to the continuous motion transmission in a machine. Therefore, the determination of ...
High-pressure phase transition in some alkali halides using interatomic potential model
(2003)
We have predicted the phase transition pressure in some alkali halides NaCl and KCl using an interatomic potential approach based on a rigid ion model. We have obtained phase transition pressures 28.69 and 2.4 GPa, ...
Can lansoprazole, amoxicillin, and clarithromycin combination still be used as a first-line therapy for eradication of helicobacter pylori?
(2005)
Background/aims: To determine H. pylori eradication rate with lansoprazole-amoxicillin-clarithromycin treatment regimen, which is the most frequently used as first-line therapy, in the Kirikkale region. Methods: One hundred ...
Prehospital life support in trauma patients: Basic or advanced trauma life support
(2006)
The controversy between Advanced Trauma Life Support (ATLS) and Basic Life Support (BLS) in the prehospital care of trauma patients has not been resolved yet. The purpose of this study was to examine the literature with ...
The effects of lactated ringer and hes solutions in differing combinations to prevent hypotension due to spinal anesthesia
(2006)
Objective: The aim of this study was to assess the effectiveness of preloading with crystalloid and colloid fluids on hypotension following spinal anaesthesia. Method: One hundred ASA Class I-II patients were randomly ...
Double transition effect in Anderson transition
(2001)
In this work we have studied the electronic mobility ? within a completely disordered lattice system by using the strong interatomic hopping potential V(r) = (-r/a0)exp(-r/a0) for site representation of the Hamiltonian. ...
The importance of mesh modeling in the calculation of stress intensity factor
(2001)
In this paper, stress intensity factor (SIF) of an infinite plate with a center notched hole is calculated by means of finite element method (FEM) using both triangular quadratic element (TQE) and triangular quarter point ...
The effects of repeated sevoflurane anesthesia on renal tubular enzymes in rabbits
(2003)
Sevoflurane, one of new inhalation agents, is metabolized to organic and inorganic fluoride metabolites. Nephrotoxicity is due to free fluoride. In this study; we investigated the renal effects of repeated and different ...
An adaptive observer for Lorenz chaotic system
(2003)
An adaptive observer design technique proposed for nonlinear systems have been successfully applied to the Lorenz system, which produces chaotic oscillations. This observer does not use any feedback directly. The feedback ...
